The Lowdown

Right then, let's have a look at what's coming our way for Jaconé over the next couple of weeks.

First off, the water is sitting at 74°F which is a touch warmer than usual for this time of year, so you'll be comfortable in a spring suit.

The week starts off a bit average. Monday the 10th is a write-off with messy onshore wind and a 7ft S swell but it's choppy and cross-on. Not worth paddling out. Tuesday the 11th afternoon shows some promise with a solid 10ft S swell (moderate wave energy of 2884) and light cross-off wind, but the swell is just too big for this break – that’s expert territory only, and even then, it's marginal. Wednesday the 12th morning is a much better bet: a 8ft S swell with a clean offshore breeze from the ENE. The combined energy is a strong 1523, and the conditions are clean. This is for experienced surfers only though, as it’s still solid.

The real standout of this whole run is Friday morning the 14th of August. You’ve got a 7ft S groundswell rolling in with a long 13-second period, and the wind is glassy – dead calm from the north. The wave energy is strong at 1404, and it's going to be absolutely clean. This is the one to circle on your calendar if you're an experienced surfer. Crowds are possible here, so get there early.

Saturday the 15th is still surfable with a 7ft S swell and clean conditions, but the wind picks up in the afternoon.

The surf then drops away. Sunday the 16th and Monday the 17th see the swell fade to 4ft and then 3ft, with weak energy (419 and 234). It's surfable but small.

Then we hit a rough patch. Tuesday the 18th and Saturday the 22nd are blown out with strong onshore winds and messy conditions – not worth it. Wednesday the 19th and Sunday the 23rd offer a bit of a window with glassy conditions on Wednesday morning, but the swell is weak and short-period (7 seconds). It’s barely surfable.

Now, looking further out, there’s a promising but less certain window around Tuesday the 25th of August. The morning shows a 6ft S groundswell with a very long 17-second period and a clean offshore wind from the NE. The combined energy is very strong at 1922. This is a proper groundswell, which at a point break or reef would be a dream, but at a beach break it can be a bit too straight. It’s worth keeping an eye on if the forecast holds. The afternoon sees an 8ft SSW swell with a 15-second period, but the wind turns cross-off and it might be a bit much.

Overall, the best on offer is definitely Friday the 14th morning for that glassy, clean 7ft groundswell. For the big stuff, Tuesday the 25th morning looks like it could be a cracker for the experienced crew.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
